Description This product/service is a remanufactured factory OEM ESL. You send in your EIS (Electronic Ignition Switch) and a key. We will program a remanufactured ESL. When you receive it, you plug it in, and it will start your car as it was intended from the factory. We also have an option to replace the factory ESL with an electronic emulator, which is what we recommend for long lasting reliability. Call us if you have any questions.
